The ketones of systematics and phylogeny continue to be the subject of deep and rich epistemological debates. Under this background, typical of pre-paradigmatic periods, new methods and theoretical proposals proliferate. They undoubtedly contribute to the increasingly intense search for a "real systematics", that is, a classification that, taking into account the complexity of the object to be studied, can reflect it as faithfully as possible. The discussion about these new methods and their contributions points to a holistic solution in the field of systematics and phylogeny.
